Description RHOS Integration 2014-08-14 04:04:39 UTC
Cloned from launchpad blueprint https://blueprints.launchpad.net/oslo/+spec/enable-mysql-connector.

Description:

Current MySQL client library we use (MySQLdb) plays bad with eventlet and may result in db deadlocks [1]. It also blocks execution of other green threads while we're deep in the library code [2]. To avoid those issues, we need to switch to a pure python library with better eventlet support. MySQL Connector is an official mysql python client library and has the needed qualities.
